I think is C or D, but I'm not to sure
Answer: No
Solution:
Substitute the values of x & y into the first equation
6 -(-1) = 3
6 + 5 is NOT equal to 3
Therefore we can say this is not true
For this to be true, when substituting the values of x & y, the equation must be true for BOTH equations. Since it’s not true for the first equation it doesn’t matter if it’s true or not for the other equation.
I hope this helps!
D. 12
Pretty much the smallest number both denominators can go in.
So the multiples of
4: 4,8,12
3:3,6,9,12
